Fair enough. How about:

Deep Blue - Kasparov, 1996. Kasparov won.
Deep Fritz - Kramnik 2002, game 1. An easy draw for Kramnik
Deep Fritz - Kramnik 2002, game 3. Kramnik won.
Kasparov - X3D Fritz, 2003, game 2. Even though Kasparov lost this game he was
in a _superior_ and _relatively closed_ position when he blundered away at least
an easy draw (with some _winning_ chances) on move 32.

Is that enough?
